SCALE.

SPECIFICATION forming part of Letters PatentNo. 308,321, dated November 18, 1884.

Application tiled March 17, 1884.

To @ZZ whom it may concern.-

Be it known that I, WILLIAM R. MORSE, a citizen of the United States, residing at Chester, in the county of Meigs and State of Ohio, have invented certain new and useful Improvements in Scales, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to improvements in weighing-scales, and is designedto produce a device with which the net weight of an article may be ascertained without replacing the said article on the scales after removing it from its receptacle, no mental calculation being necessary.

The improvement consists, essentially, in graduating the scale-beams, which project from each side of the fulcrum-point, from the butt toward the free end. These objects I attain by the means illustrated in the accompanying drawings, in which- Figure 1 represents a side elevation of Iny improved weighing-scale, the I'ront end of the sway bar or frame being shown in section to show the attachment of the auxiliary beam. Fig. 2 is a plan view of the same, and Fig. 3 is a perspective view of a portion ofthe sway bar or frame and scale-beams- In the drawings, A represents the base and hollow standard of the scales, with the horizontal bar b and vertical rod c, supporting the platform D. The standard A is provided with the fulcrum c, supporting the frame E and beams. p

II is the counteracting beam, graduated from right to left, and supplied with the usual weighing-poise and a weight-pan` S.

The sway bar or frame E consists, in my improved construction, of the cent 1al lframe with the side knife-edged projections, the two parallel scale-beams F F', provided with the usual movable weights and a dependent balancing and weightpan and extending rearward from the frame, and the scale-beam II extending in the opposite direction.

In the manufacture of new seales,the beams vF and F, the frame E, and the beam II are made integral by castingor otherwise,l as shown in Fig. 3 of the drawings; but in some cases I prefer to make the scalebeam H at- (No model.)

tachable, which is accomplished by enlarging the rear end ofthe beam and providing it with a slot, m, to tit over the sway bar or frame, and a set-screw, n, to hold itsecurely in place, as shown in Fig. l ofthe drawings.

It will be seen by referring to the drawings that the scale-beams are graduated from the standard A outward.

The operation of my invent-ion is as follows: A basket ot butter is brought to a store to be sold. The purchaser, to ascertain its netweight, readily places the basket and its contents upon the platform D ofthe scale, and by adj usting the poises on the beams F and F the gross weight is ascertained, in which adjusted position the poise orpoises should remain. Then the basket is emptied of its contents and placed upon the platform again. Then, by moving the poise on the beam II until it counterbalances the gross weight, the net weight of the article removed will be registered on the beam I-I without mental calculation.

It is evident that the basket, being on the opposite side of the fulcrum to the beams which register the gross weight, will counterbalance its own weight, and, if it and the poise on the beam H counterbalance the whole gross weight, then the weight registered by the poise on the beam II must be the net weight ofthe article removed.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

A scale consisting of a standard supporting scale-beams projecting on each side ofthe fulcrum-point, said beams being graduated from the butt toward the free end, and pro vided with movable weights and pendent counterpoises, and a platform supported at one side the fulcrum, the whole device giving` the gross, weight of a contained article, and then, by replacing the package only, the net weight ofthe said article without mental calculation, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence ot' two witnesses.

VILLIAM R. MORSF.
